“…Schematic representation of the fretting-corrosion process taking place at the stem-cement interface and a mechanism for metallic debris from the metallic stem to the counterpart (Bryant et al, 2013d) It is evident from this work and review of the literature that the type of degradation mechanism can influence the type and quantities of metal ions released from the interfaces. This is supported by the experimental results presented by Wimmer (Wimmer et al, 2003), Liao (Liao et al, 2013;Liao et al, 2011), Yan (Yan et al, 2009), Hesketh (Hesketh et al, 2013) and Heisel et al (Heisel et al, 2008) who have all demonstrated that such films can reduce wear and corrosion, along with a stoichiometric release of metallic ions into the bulk environment.…”

The aim of this study was to further understand and characterise the exact surface chemistry, speciation and tribochemical reactions resulting in the deposits observed on retrieved femoral components; an unappreciated area of study with respect to the degradation and type of debris generated from orthopaedic implants.…”

“…Prior to microscopic observations, each THR was sectioned according to Gruen et al (Gruen et al, 2011) and macroscopically graded in terms of fretting-corrosion and location and have been reported previously (Bryant et al, 2013d). After macroscopic analysis a select number of stems were sectioned and Scanning Electron Microscopy (SEM) with integrated Energy Dispersive X-ray (EDX) spectroscopy was conducted using a Carl Zeiss EVO MA15 microscope in order to inspect the stem surfaces at a higher resolution and to gain a basic elemental composition of any debris or deposits found on the surface of the stem.…”

The use of cemented femoral stems is common practice worldwide with strong clinical data supporting their use.Over the years, different surface processing techniques have been employed to enhance the performance of the stem-cement interface. As a result different clinical outcomes and visual presentation at revision has been observed. Whilst research has focussed on increasing adhesion and better load bearing capacity, the effects of surface processing on the degradation of cemented femoral stems has not been investigated. The aims of this study was to investigate the effects of surface processing on the subsurface microstructure, surface chemistry and tribocorrosion degradation mechanisms of cemented tapered femoral stems subjected to polishing and blasting (Vaquasheen) processes. Cemented femoral stems were orientated and loaded according to for 500,000 cycles in 0.9% NaCl at 37 ˚C. A three-electrode electrochemical cell was integrated into the mechanical test to facilitate in-situ corrosion measurements. The severity and mechanism of damaged were assessed scanning and transmission electron microscopy, X-ray photoelectron spectrometry, solution mass spectrometry and white light interferometry. Surface processing was seen to drastically influence the level of corrosion within the interface with polished surfaces demonstrating the highest levels of corrosion. Surface analysis consistently demonstrated the presence of a SiO2 layer on the vaquasheened stems thought to originate from the glass bead blast matrix. This resulted in lower levels of corrosion both under static and tribocorrosion assessment. In conclusion, blasted surfaces resulted in lower wear induced corrosion when compared to the polished surfaces. However the total metallic ion levels did not follow the same trend. This is thought to be due to the formation of metallic debris and dissolution of debris due to abrasion of the femoral stems.

The occurrence of damage on polished femoral stems has been widely reported in the literature, and bone cement has been implicated in a tribocorrosive failure process. However, the mechanisms of cement‐mediated damage and the impact of cement formulation on this process are not well understood. In this study, 13 Zimmer CPT polished femoral stems, and the corresponding cement specimens were retrieved at revision surgery and analyzed using high‐resolution imaging techniques. Surface damage attributed to tribocorrosion was observed on all stems. Corrosion product, in the form of black flaky surface debris, was observed on the surface of cement specimens; both energy‐dispersive X‐ray spectroscopy and inductively coupled plasma mass spectrometry(ICP‐MS) confirmed the presence of cobalt and chromium, with the ICP‐MS showing much higher levels of Cr compared to Co when compared to the original stem material. Agglomerates of ZrO2 radiopacifier were also identified on the cement surface and, in some cases, showed evidence of abrasive wear; the size of these particles correlated well with elliptical pitting evident on the surfaces of the corresponding stems. This evidence supports the hypothesis that agglomerates of hard radiopacifier particles within the cement may induce a wear‐dominated tribocorrosive interaction at the stem–cement interface that damages the surface of polished CoCr femoral stems. © 2016 Wiley Periodicals, Inc.
